Change we can believe in:

More Young Adults Live With a Parent Than With a Spouse, Partner

For the first time in more than 130 years of record-keeping, young adults in the United States are more likely living with mom and dad than they are living with a spouse or partner.

Thirty-two percent of millennials adults aged 18-34 were living in their parents’ home in 2014, compared to 31.6 percent of millennials who live with a spouse or significant other, according to a new Pew Research Center analysis of government data.

Another 14 percent of millennials live alone, or else are single parents. Twenty-two percent live in other circumstances.

“Dating back to 1880, the most common living arrangement among young adults has been living with a romantic partner, whether a spouse or a significant other,” it continues. “This type of arrangement peaked around 1960, when 62% of the nation’s 18- to 34-year-olds were living with a spouse or partner in their own household, and only one-in-five were living with their parents.”

The article blames changes in who gets married and when.  Given what marriage costs (both up front and on an ongoing basis afterward), I suspect the crappy economy’s at least as much to blame.  People don’t have the money to get married, and the tax code still disincentivizes marriage.
